FIELD OF INVENTION

The present invention is directed to inhibitors of mutant isocitratedehydrogenase (mt-IDH) proteins with neomorphic activity useful in thetreatment of diseases or disorders associated with such mutant IDHproteins including cell-proliferation disorders and cancers.Specifically, the invention is concerned with compounds and compositionsinhibiting mt-IDH, methods of treating diseases or disorders associatedwith nit-IDH, and methods of synthesis of these compounds.

BACKGROUND OF THE INVENTION

Isocitrate dehydrogenases (IDHs) are enzymes that participate in thecitric acid cycle (cellular metabolism). They catalyze the oxidativedecarboxylation of isocitrate to 2-oxoglutarate (i.e., α-ketoglutarate,α-KG). There are three isoforms within the IDH family. IDH-1, expressedin the cytoplasm and peroxisome, IDH-2, localized in the mitochondria,both utilize NADP⁺ as the cofactor and exist as homodimers. IDH-3 islocalized in mitochondrial matrix and utilizes NAD⁺ as a cofactor andexists as tetramer. Mutations in IDH-1 (cytosolic) and IDH-2(mitochondrial) have been identified in various diseases or disordersincluding glioma, glioblastoma multiforme, paraganglioma, supratentorialprimordial neuroectodermal tumors, acute myeloid leukemia (AML),prostate cancer, thyroid cancer, colon cancer, chondrosarcoma,cholangiocarcinoma, peripheral T-cell lymphoma, and melanoma (L. Deng etal., Trends Mol. Med., 2010, 16, 387; T. Shibata et al., Am. J. Pathol.,2011, 178 (3), 1395; Gaal et al., J. Clin. Endocrinol. Metab. 2010;Hayden et al., Cell Cycle, 2009; Balss et al., Acta Neuropathol., 2008).The mutations have been found at or near key residues in the activesite: G97D, R100, R132, H133Q, and A134D for IDH1, and R140 and R172 forIDH2. (See L. Deng et al., Nature, 2009, 462, 739; L. Sellner et al.,Eur. J. Haematol., 2011, 85, 457).

Mutant forms of IDH-1 and IDH-2 have been shown to lose wild typeactivity, and instead exhibit a neomorphic activity (also known as again of function activity), of reducing alpha-ketoglutarate to2-hydroxyglutarate (2-HG). (See P. S. Ward et al., Cancer Cell, 2010,17, 225; Zhao et. al., Science 324, 261 (2009); Dang et. al Nature 462,739 (2009)). In general, production of 2-HG is enantiospecific,resulting in generation of the D-enantiomer (also known as the Renantiomer or R-2-HG). Normal cells have low basal levels of 2-HG,whereas cells harboring mutations in IDH1 or IDH2 show significantlyelevated levels of 2-HG. High levels of 2-HG have also been detected intumors harboring the mutations. For example, high levels of 2-HG havebeen detected in the plasma of patients with mutant IDH containing AML.(See S. Gross et al., J. Exp. Med., 2010, 207 (2), 339). High levels of2-HG have been shown to block α-KG dependent DNA and histonedemethylases, and ultimately to result in improper dedifferentiation ofhematopoietic progenitor cells in AML patients (Wang et. al., Science340, 622 (2013); Losman et al., Science 339, 1621 (2013)).

Furthermore, patients with Oilier Disease and Mafucci Syndrome (two raredisorders that predispose to cartilaginous tumors) have been shown to besomatically mosaic for IDH1 and 2 mutations and exhibit high levels ofD-2-HG. (See Amary et al., Nature Genetics, 2011 and Pansuriya et al.,Nature Genetics, 2011).

The inhibition of mt-IDHs and their neomorphic activity with smallmolecule inhibitors therefore has the potential to be a treatment forcancers and other disorders of cellular proliferation.

DETAILED DESCRIPTION OF THE INVENTION

IDH1 or IDH2 mutations are genetically validated targets in many solidand hematologic cancers, but there are currently no targeted therapiesavailable for patients in need of treatment for specific conditionsassociated with mt-IDH activity. Non-mutant IDH (e.g., wild-type)catalyze the oxidative decarboxylation of isocitrate to α-ketoglutaratethereby reducing NAD⁺ (NADP⁺) to NADH (NADPH) (WO 2013/102431 toCianchetta et al., hereby incorporated by reference in its entirety).Mutations of IDH present in certain cancer cells result in a new abilityof the enzyme to catalyze the NADPH-dependent reduction ofα-ketoglutarate R(−)-2-hydroxyglutarate (2HG). 2HG is not formed bywild-type IDH. The production of 2HG contributes to the formation andprogression of cancer (Dang, L et al., Nature, 2009, 462:739-44, herebyincorporated by reference in its entirety). The present inventionprovides inhibitors of mt-IDH, and prophylactic measures to reduce theformation and progression of 2HG in cells.

Alternatively, the same optionallysubstituted alkyl group can have substituents different from hydrogen.For instance, it can, at any point along the chain be bounded to ahalogen atom, a hydroxyl group, or any other substituent describedherein. Thus the term “optionally substituted” means that a givenchemical moiety has the potential to contain other functional groups,but does not necessarily have any further functional groups.

The media was then removed from each well and150 μL of a methanol/water mixture (80/20 v/v) was added to each well.The plates were kept at −80° C. freezer overnight to allow for completecell lysis. An aliquot of 125 μL of extracted supernatant was analyzedby RapidFire high-throughout-mass spectrometry (Agilent) to determinethe cellular 2-HG level. The IC₅₀ of a given compound was calculated byfitting the dose response curve of cellular 2-HG inhibition at a givenconcentration with the four parameter logistic equation
